In Addition, the following points will help you to understand, How Nanotechnology helps to the Automobile sector
- Polymer nanocomposites structural parts, high-power rechargeable battery systems, thermoelectric materials for temperature control, lower rolling resistance tires, high efficiency/low-cost sensors and electronics, thin-film smart solar panels, and fuel additives and improved catalytic converters for cleaner exhaust and longer range are just a few examples of nano-engineered materials in automotive products that have been discussed previously. Metal and cementitious nano-engineering has considerable potential for increasing roadway and transportation infrastructure components’ performance, resilience and lifespan while decreasing their life cycle costs. Self-repairing structures or the capacity to create or transport energy may be incorporated into existing infrastructure materials via new technologies.
- In the future, nanoscale sensors and gadgets may be able to continuously monitor the structural integrity and performance of bridges and tunnels, as well as parking structures and pavements. Using nanoscale sensors, communications devices, and other nanoelectronic innovations, the transportation infrastructure can be enhanced to communicate with vehicle-based systems to assist drivers in maintaining lane position, avoiding accidents, changing travel routes to reduce congestion, and improving drivers’ interfaces with onboard electronics.
- Nanotechnology-enabled lightweight, high-strength materials might have “game-changing” effects on almost every transportation vehicle. The fuel consumption of a commercial jet aircraft may be reduced by up to 15% if its weight were reduced by 20%. Using nanoparticles with double the strength of traditional composites might cut the gross weight of a launch vehicle by as much as 63%, according to preliminary NASA research. To begin with, the amount of energy needed to launch spacecraft into orbit could be significantly reduced, and in the future, single-stage launch vehicles could be developed to achieve orbit. This could lower launch costs, improve mission dependability, and open the door to new concepts for propulsion systems.
- Fuel efficiency is a major goal for automakers, and one of their primary tools is lighter vehicles. As an example, the “Atoms to Engines” team at Ford looked studied the structure of cast aluminium alloys at the atomic level, for example. An in-depth investigation of the structure/property/process relationship of aluminium alloy engine blocks has resulted in decreased weight and improved fuel economy.
- Polymers may also be used to replace mineral glass windows. Key performance requirements have not been met until recently, including scratch resistance and long-term UV resistance. Nanotechnology-based advancements in polycarbonate window development are assisting the industry to overcome these difficulties.
- When compared to standard steel chassis components, weight savings of up to 40% are possible using nanoengineered thermoplastic materials.
- Nanostructured surfaces increase paint adherence and color endurance in paints and surface coatings. In the future, self-cleaning windscreens and automobile body shells will be commonplace. Paints for automobiles that are scratch and abrasion-resistant as well as dirt and UV-resistant are either currently in use or are being developed.
- Nanostructured materials have been used in automotive tires since the early 1990s. For the first time, the automobile industry used carbon black in tires as a color and reinforcement ingredient.
- The rubber combination is the key to tire performance, yet its optimization needs might be contradictory (very complicated chemical and physical interactions between the rubber and the filler material): The tire’s rolling resistance must be kept to a minimum in order to maintain an adequate grip on the road.
- Reinforcing filler accounts for around 30 percent of the tire cover, enabling desired attributes such as grip, abrasion resistance, resistance to early wear and tear, and tear propagation. Soot, silica, and organosilane are three components that considerably enhance the characteristics of natural rubber. A major component of tire performance is the cross-linking of nanoparticles with natural rubber molecules, which now exist in nanoscale form.
- Building an electric car needs to take into account four basic requirements – powerful and safe energy storage to give the car a sufficient driving range; engines and associated electronic components that make the best use of the stored onboard energy; light-weight components to compensate for the (at the moment still) extra weight of the batteries; and all that at a price that can compete with gasoline-powered automobiles.
- Lithium-ion batteries are currently being intensively developed worldwide for use in electric vehicles. The consensus view among researchers is that the battery will be of the lithium-ion type, but which of the lithium-ion chemistries to use is still a major question.
- Nanotechnology holds great promise for improving the performance and lifetimes of Li-ion batteries. It also has the potential to enhance the energy and power density, shorten the recharge time, as well as decrease the size and weight while improving the safety and stability of the batteries. A large number of companies such as Altair Nanotechnologies, mPhase Technologies, A123 Systems, Li-Tec Battery GmbH, NanoEner Technologies, Next Alternative Inc., Nexeon Ltd.,, etc. are actively pursuing the development of nano-enabled batteries while some others are already producing them (see here for an overview of major producers/developers of nano-based batteries and their product range).
- Nanotechnology is also key to improving the fuel cell performance of future generations of hydrogen-powered cars.
- One of the leading fuel cell technologies developed, in particular for transportation applications, is the proton exchange membrane (PEM) fuel cell, also known as polymer electrolyte membrane fuel cells – both resulting in the same acronym PEMFC. These fuel cells are powered by the electrochemical oxidation reaction of hydrogen and by the electroreduction of the oxygen contained in air.
- Although nanotechnology promises cheap bipolar materials using nanocomposites, more efficient non-platinum electrocatalysts, and thermally stable and more durable membranes to become available in the near future, the precious metal platinum still remains the workhorse of PEM fuel cells. One way to minimize platinum usage is to increase catalytic efficiency by nanostructuring the platinum metal; another way of eliminating the use of platinum altogether is by exploring the use of much cheaper non-precious metal catalysts where the nanostructured surfaces match or exceed the catalytic properties of platinum.
- Cars powered by fuel cells will need hydrogen sensors, which will be a key safety component. Leaks will be spotted long before they pose a danger to the public, thanks to their ability to monitor the gas. Nanostructured materials, such as single-walled carbon nanotubes coated with palladium nanoparticles, have previously been used to build thin, flexible hydrogen sensors. Of course, gas guzzlers will be with us for a long time. Applications of nanotechnology will have a significant influence on fuel economy and dangerous exhaust emissions. Due to the friction loss at moving mechanical elements, 10-15 percent of today’s vehicles’ fuel consumption is impacted by engine friction (piston, crank drive, valve drive). Friction and abrasion may be reduced and fuel economy improved by using nanocoatings and nanostructured lubricants on mechanical components.
- Ford is developing a thermally sprayed nanocoating that might replace the heavier cast iron liners in aluminum block engines. Thin wear-resistant coating saves weight and decreases friction while maintaining product longevity and dependability. Piezo fuel injection is utilized in diesel and petrol engines. In direct injection, a pump builds up pressure before shooting fuel via a nozzle into the cylinder’s combustion chamber. Precision affects combustion. The more accurately the injection dosage and duration can be adjusted, the more efficiently fuel will burn. Nanocrystalline piezoelectric materials enhance these. Three-way catalysts purify emissions in gasoline-powered autos. These convert carbon monoxide, nitric oxides, and hydrocarbons to eliminate them from the exhaust gas. Nanotechnologies help convert harmful to non-toxic gases. Catalyst influence varies on surface size. Scaling catalytic material to the nanoscale range enhances specific surfaces. Composition and structure are designed so exhaust gases interact best with the catalytically active coating, accelerating their chemical transformation.
- Nanoparticulate air filters and anti-glare coatings for mirrors and instruments will be the primary focus of car interior applications… Also, how about temperature-controlled automobile seats based on thermoelectrics — materials that turn power into heat or cool immediately?
- More automobile components are controlled electronically, electromechanically, or electromagnetically, driving innovation. Nanostructured actor components might replace direct injection microsystems. Spintronics will change computers. Spintronics utilizes electrons’ spin, which can be controlled by electric and magnetic fields, whereas CMOS relies on electrons’ charge to power devices. Nanoscaled magnetic materials eliminate standby power dissipation in spintronics or electrical devices. Non-volatile electronics may be made with this benefit.
- The developing hybrid automobile industry employs batteries to store energy for electric driving mode and re-uses braking energy. During braking, kinetic energy is transformed into electrical current and stored in accumulators or super or ultracapacitors. Nanotechnologies should have a big influence. Ultralight, flexible batteries, and supercapacitors are already being made from paper.
- Some automobiles feature micro-structured solar cell sunroof options. Using nanostructured, flexible plastic solar cells with a thickness of less than 1 micron, solar energy harvesting thin films may cover bigger automobile exterior regions. Today’s autos have a 1 percent electrical-to-optical efficiency for illumination. Diffractive micro-optics, new light sources, and power supply integration will enhance this.
